How to calculate carbon 14 dating 1

radiocarbon dating also referred to as carbon dating or carbon14 dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon a radioactive isotope of carbon the method was developed in the late 1940s by willard libby who received the nobel prize in chemistry for his work in 1960 it is based on the fact that radiocarbon 14.

A further example from a lava flow off the coast of hawaii shows similar discrepancies if dated with the carbon14 method the flow appears to be less than 17000 years old but dating with the potassium argon method gives dates of 160000 to 43 million years.

The older a sample of a radioactive material the less radioactive it is the decrease in radioactivity follows a characteristic pattern shown in the graph or decay curve the y axis can represent the radioisotope left or the measured radioactivity.

Dr hovind g1 the assumption that the geologic column is a base from which to calibrate the c14 dates is not wise g1with a halflife of only 5730 years carbon14 dating has nothing to do with dating the geological ages whether by sloppiness or gross ignorance dr hovind is confusing the carbon14 clock with other radiometric clocks.
